What is Resource Certification (RPKI)?
Resource Certification (RPKI) is a free opt-in member service that allows LIRs to obtain a resource certificate listing the Internet number resources they hold. The certificate is cryptographically verifiable proof that the Internet number resources have been registered to a member by the RIR.
The system is based on globally accepted and well-known X.509 Public Key Infrastructure (PKI) principles. The standards used in Resource Certification are open and have come out of the Secure Inter-Domain Routing (SIDR) Working Group in the IETF.
